I think this is the better game to remake since DK 94 is already an amazing game. As we saw with something like Links Awakening, games that are already regarded as masterpieces, Nintendo doesn't change that much with the remake. So if they remade DK 94 it would have been pretty close to the same game but with better graphics.
I'd hope with this game, since it wasn't as highly praised, it'll get the Zero Mission treatment where they make a lot of changes and add significant new content to improve on it. Then we'll finally have a sequel to DK 94 that's closer in quality to that game, which the original GBA game while still good, wasn't quite there. That's why I prefer games like this getting remakes since they can benefit more then games that are already amazing and don't really need any major changes.
